Increase the Security of Your Home with Video Surveillance and Video Analysis
by Get Stealth Chicago Stealth Security & Home Theatre Systems, IncVideo surveillance
systems are an excellent solution if you want to strengthen the control
function of your alarm system.
Thanks to
strategically placed cameras, the chances of having everything under control
increase. The video control can be used both inside your home (but also in the
office and in your shed) and outside: the garden, the neighboring streets and
the perimeter of the building. This system allows you to record what happens in
the points of greatest interest and to see on the monitor of your device (TV,
PC, smartphone, tablet) the images taken by DVR (Digital Video Recorder) or NVR (Network Video
Recorder) video recorders. The latest generation video analysis systems allow
to recognize the passage of human beings and to report anomalies through
notifications on the App associated with the installed system. In the field of
security and video surveillance cameras in Chicago, the distinction between analogue cameras and IP cameras
is a must:
Analog Cameras
The cameras are
capable of recording images in the PAL (Phase Alternating Line) format with a
resolution of 576 interlaced lines. This does not allow for clear lines on
moving shots (for example in the case of passing vehicles) but the positive
side is that the installation costs are quite contained. As often happens, at a
reduced price there are lower performances and therefore it must be taken into
account that the cheaper versions are unable to return high quality images or
audio. In the video field, infrared LEDs can come to the rescue, illuminating
portions of space and recording video in the total absence of lighting, thus
increasing the performance of the analog camera. Unfortunately it remains, as
"against"
IP (Internet Protocol) Cameras
IP cameras are models
of wired or wireless video security camera installation in Chicago that can connect to the Internet and
save recorded videos on the cloud or on memory cards. Of course, to connect to
the network, there must be a suitable predisposition and above all a fast
connection because otherwise you risk, on the one hand being able to record
videos with clear, high-quality images (HD 1280 × 720 pixels) and on the other,
of collide with the reduced capacity of the home ADSL that struggles to
transmit images that require a lot of bandwidth remotely. In this case it is
better to opt for a camera with lower video resolution. For example, 640 × 480
pixels can be a viable alternative. Choosing a video surveillance system with
IP security cameras allows you to
find your way around instruments with motion detection: sensors that detect the
movements in the area kept under control and that notify via App, messages or
e-mail in case of any intrusions or anomalies. This type of camera can be
equipped with a passive infrared PIR (Passive InfraRed) sensor that allows to
measure the infrared rays (IR) radiated by the objects. All objects emit energy
in the form of light radiations but they are radiation invisible to the human
eye. However, they do not escape the sensors installed security cameras in modern video-control systems, which can
thus work even in the dark.
Intelligent Video Analysis System
In the field of video
surveillance systems, video analysis is gaining momentum whose importance is
increasing and whose techniques are gradually being refined. But it is
necessary to have a clear and truthful idea of what the video analysis can
currently do. To avoid charging it with responsibility, which does not reflect
its real possibilities? Certainly his contribution is decisive in typical
situations:
·
Intrusion
in unauthorized areas;
·
The
theft or abandonment of suspicious objects;
·
The
detection of suspicious persons;
·
Great
agitation during public events.
The presence of an
operator in charge of control is not always able to highlight and promptly deal
with this type of anomaly, so the electronic support of a video analysis system
is very welcome. Provided that it is truly intelligent and shows support to the
operator, filtering upstream information and events of interest, avoiding as
much as possible false alarms. Without a doubt, the advantages of intelligent
video analysis are and are presented as:
Reduction of data to
be archived: recording only what is really significant saves less useless data;
Time saving: the
monitoring of the shooting is easier and allows the operators to deal with a
greater area thanks to strategically positioned cameras;
Greater effectiveness:
automatic video analysis helps prevent security breaches.
Legal Aspects and Privacy
The offer is very wide
and there are do-it-yourself video surveillance systems even in large-scale
distribution but, as we have already mentioned on other occasions, it can be a
mistake to decide not to rely on an expert because, compared to a lower cost ,
there is the risk of running into problems in the medium to long term. The
installation and maintenance of the home security systems, carried out by a company and by qualified technical
personnel, also gives the customer the certainty of always being informed about
the regulations in force.
The professionals in
fact constantly update themselves both on the new techniques in the field of
security and alarms, but also on everything concerning norms and bureaucracy.
Being a job that can have very delicate implications ,the possibility of being
able to give the best advice to our customers and to know how to keep them calm
is a plus to which, at Get Stealth for example, we do not intend to give up.
At the end of the
work, the system designer will deliver to the customer a plan on which the
points of presence of the security camera systems are indicated and, if it is an installation within a work
environment, he will remind the client that, as employer of work owner of the
office or company, must report to the Inspectorate of local work, the presence
of the video surveillance system by fulfilling the bureaucracy of the case. Not
the last one concerning the Privacy which, for some years now, has been
regulated by specific laws.
From the privacy point
of view, if it is a video control system placed outside the building, the owner
must move taking into account some fundamental points:
1. Signal the cameras with a special billboard,
clearly visible and exposed in the beam of action of the cameras;
2. Enter the details
of the data collection manager on the billboard;
3. Place the video recorder in a closed and
protected room, access to which is only possible "to the employees”;
4. Destroy the records every 24 hours using
the special software or request the Privacy Guarantor to
keep them in the archive for more than a week up to a maximum of 90 days;
5. Resume vehicle or person passages only
inside the property to avoid a crime;
6. Do not disclose video footage or make it public,
for any reason, on social media. The only ones who can use them are the Police
Forces, in the event that suspicions are made of illegal activities;
7. You can avoid
reporting the installation to the Privacy Guarantor only if the footage is used
to protect security and prevent vandalism.
